That was a beautiful story, NG
. Definitely one of my favourites, and it really captures what you see in the Cardassians (when they're free of the toxic ideals that the canon Cardassian culture has embraced over the centuries). Dukat's journey was very compelling, and convincing too. It was a genuine character piece rather than simply "the hero" going through the motions (it felt genuine, as a hint of how young Dukat became the famed resistance leader of your other AU works but still being a somewhat lost young person searching for a new stability).
Just as an aside- I can't remember if it was established elsewhere, but does Dukat ever learn the fates of his siblings and parents? The lack of any return to the city is of course essential to the story, and that uncertainty hanging over it really works to convey the mood, but I wonder
